Designs with string trees are because of the long distance and flat headstock making it impossible to get a correct angle, so the band aid is to add trees. I assume that the silo 3 has the same angled headstock that SBMM and EBMM guitars have. That being the case, I'm going to say to get a sharp pencil and "write" on the grooves of the nut. Then stretch the strings well. I find that doing those 2 things have made even the cheapest guitar with the crappiest tuners stay perfectly in tune and sound fine. The strings have to be able to move in the nut unless you have string locks (aka Axis). Even my son's "shark" guitar (the body is shaped like a shark) that has trapazoidal tuners (crap) stays in perfect tune.
I'll add that over the last couple years, I've had dozens of string tree'd guitars. With those, you have to also put goop under the trees unless they're rollers.
